How do I know if my car has AdBlue?

If you have a diesel car manufactured from 2016 onwards, it almost certainly features an AdBlue system. The easiest sign to identify: a blue cap separate from the fuel, usually marked with the "AdBlue" or "SCR" symbol. Some cars have it under the hood, others next to the fuel cap.

EXTENDED DESCRIPTION

Introduction

If you have a diesel car from 2016 onwards, your car has a system that most owners completely ignore. It's called AdBlue. And when it fails, the repair will cost you at least €1,500.

This treatment is added directly to the AdBlue tank in 30 seconds. It eliminates accumulated solid particles, prevents crystallization of the system, and protects the injector, which keeps the system running.

Maintenance that no one explains to you. Until now.

USER INSTRUCTIONS

Frequently asked questions

How often should the treatment be used?

The recommendation is to add a dose every time you refill AdBlue. If your tank has between 15 and 20 liters, one dose is 25ml — already included in the product dispenser. If your tank is larger (some go up to 25 liters), add a bit more proportionally.

Does it help if my circuit already has problems, or is it only preventive?

The two things. If the circuit already has accumulated particles, the treatment actively works to clean it. If there is still no visible problem, it acts as a preventive measure. In any case, the sooner it is used, the better for the system.

Is it compatible with all AdBlue brands on the market?

Yes. The treatment is compatible with any approved AdBlue (ISO 22241). It does not affect the composition of AdBlue or the sensors of the SCR system.

How is it used exactly?

Refill the AdBlue as usual. Then, open the product dispenser and add 25ml directly to the AdBlue tank. Close the cap. That's all. The system itself takes care of distributing it throughout the circuit.

What happens if I haven't done this maintenance for a while?

There is no problem starting now. The treatment works on both clean systems and systems that have gone without maintenance for some time. If you haven't treated the circuit for several years, you may notice that the product has more work to do at first — this is normal.

How long does it take to arrive?

We ship within 3-5 business days after the order is confirmed. If you have any issues with the shipment, contact us directly and we will resolve it.
